.To all whom it vir/ay concern l Be itknown that I, EDWARD C. MRBIs,of

Boston, in the county of Suffolk and State of otMassacliusetts, have invented ,certain new and useful Improvements in Compound Plastic and NettingLiningor Finish for Partitions, \Valls, Ceilings, Ste., of which the following is 'a full,- clear, and exact description.

As well known, aeompound finish or lining for'walls, partitions, ceilings, Ste., of buildings, &c., has been used, consisting of a backing made of wire-netting of suiiicient strength and aco-vering thereto composed of a layer of 'plastic-materialsuch as ordinary linie-plas .ter-which is applied to it and. forced through its interstices `or meshes, and thereby keyed, as

it were, and secured tonand about the wiresof the netting. the netting being first secured in y "place,'and then the plastic material applied to it and properly smoothed and evened ofi'. In

the construction vof this finish or lining Ifor walls, Ste., of buildings, Aas well known, the plastic material passes through the meshes to the back side of the Wirehetting Without re straint or hinderance, und more especially ris this so if theniesli of the nettingis a somewhat open one, and which foreconolnyit is desirable itshould be,thewholeresultingin the consumption of a considerable amount of plasticl material and au amount largely in excess of that really and practically required for all ppn poses of the vlining or finish., f

To obviate these objections, and Without`- otherwise'niateriall y increasing the cost of the lining, butin fact economizing in its cost by enabling a most open mesh of wire-netting to be used ascoinpared with the mesh heretofore capableof beingA practically and servieeably' used, is the object of this invention; and to that end the invention consists-of a lining or finish for walls, ceilings partitions, 85e., cornposed of a layer o1' inaterial-snch as paper or other pulped board,A4 wood, metal, die, lint preferably paper or. other pulped board, and which at leastllas been in anysuitable manner made waterproof, and also as well tlrefproof" directly suriiieing and covering the wall, ceiling, partition, etc., and properly secured in position, a layer of wire or other netting er equivalent lnaterialsurfacing said paper layer and secured in position in any suitabie man ner, and preferably with al space between its wires or strands and said paper layer, and a layer of-plastic materialsuch as ordinary linie plaster or other suitable ma-terial-applied to the outside of the netting layer and forced into and` through its meshes against the paper layer back thereof, and also., if a space is left between the wires of the'netting layer and the paper layer, into saidspace, illing it 6o and the openings or meshes of'thje netting, all substantially as hereinafter described;

In the accompanying drawings, forming a part of this specication, one form of carrying out this invention is illustrated, and Figure l is a sectional perspective view .of a portion of the studding of a wall lined or nished inac-l cordance therewith. Fig. 2 is a horizontal section ou line 2 2, Fig; l.

In the drawings, A is the studding. B l? are the furringstrips nailed to stud ding A.. 4

Gis a layer of material--suel1 as paper o pulped boardnailed to the furri ng-strips B B.

, netting and the layer G of pulped board, and

Gis a'layer of plastic material-such as ordinary limeplasteror othersuitable inaterialw 8 5 but preferably a plastic material or compound such as described in the schedule annexed to the Letters Patent of the .United States issued .te Henry W'. Merritt, oi Boston, Massa-chu setts, dated July 14, 1885, No, 322,307, or other 9o material or compound having practically si milar adhesiveness, hardness, and re and Water proof qualities. The pulped board C, which preferably is water-prooi', as also .tire-proof, but for which other materialm-sucli as wood, metal, Ste-may be substituted, makes the inner surface or layer, the plastic material G theouter surface or layer, and the netting E,

er other equiv'aient sheet material, the intermediate surface or layer of the compound iin- :oo ish or lining of this invention. The plastic material lls the meshes of the netting E. and 1 5. `1

2' animi also enters into and is confined in the space I' F, which is between the netting and the'pulped board, and the ,pulped board limits and reystrains the inward lmovement of the plastic material, which, in-the making up ofv the 1ining or finish, is applied to theoutside-of the netting and forcedthrough its meshes. Again,.-

back of and around n n-d tomcontine 'itc-most closely to the strands of the netting, and so, as

the .plastic material dries and hardens, the better to secure the union-andl adhesion of it with the strands o'f the netting.

In constructing vthe lining or finish described the inner layer, C, is iirst secured in place, and thenthe intermediate layer, E, of

o netting, preferably leavingaspace, F, between 'its-"strands and the iunerlayenofand afterward the plastic materialisapplied tothe outside of thenetting and entered into its meshes, and also into the space F between it and the inner layer, C, the whole resulting in the production of a lining or finish in one form in accordance with the invention. l

As particularly shownl and described, the space F,.between the`inner layer, C, and intermediate layer` E, of netting, is lproduced by separate strips D of' paper applied to the in- "suitable manner, the essential feature of thisl ner layer. These strips' D may be of other material, and again they may b e first attached tothe netting, and; then to the-paperboard; and also they may be dispensed with and a space, F, secured by raisedportionsor knobs or ribs of the layer' C, or pulped board or of the layer E, or netting, or otherwise, in any invention in this regard being an interme- -diate space, or, in other words, a space back of and between thestrands of the netting E andthe inner layer, C, of sheet material.

The construct-ion of a lining or finish as .therein described allows netting of a most open mesh to bevused, for the reasonthat the,

passage of 'the plastic material throughthe meshes isprestrained and limited by the inner layer,'C, and with an intermediate space, F,

the plastic material is aiiord'ed ample-oppor tunity to lock itself about, upon, and back yof the strands making up the netting. In this lining oriinish thenetting is in reality the part depended upon to support the' lastic material; but in the construction of the., ining, and also, asis obvious, even after its construction, the inner layer, C, serves a most useful purpose, in the first instance, as a limit or restraint to the-inward movement of the plastic material, and also as a surface for the plast-icv material ltao-adhere to between the wires and in ythe open meshes of the net-ting, and again 60 with a space, F, between the inner layer,l C.

.and the wiresy of the intermediate layer, E, of

netting for the entrance and passage of the ,plasticmaterial to and around the back ofthe wires; also.as a means to coniine and hold the 65' plastic materialas it .driesand setsn close" contact with and around, and thus t-he betterl to unite itv to the wires, and in thel second instance, as aprotection, and more particularly so if it is water andlire proof, against moist 1o ure, dampness, and re. Theplastic compound patented by Mr. McrA ritt," hereinv referred to, is theplastic conv pound, as beforestated, most preferable to be used, but it is not intended to limit the in- 75 vention thereto, and for a description ot' said compound reference is hereby had to the Letters Patent hereinbefore mentioned, and again it is not intended to .limit theinventiun to any particular kind of plastic material. sa

ln the construction ofthe lining or' finish of this invention it is preferable to use a netting of wire, but netting made of strands ofother material-as for instance, of anima! or vegetable iiber--and agaima perforated plate of 85 metal orr other material, may be used. o

Having thus described my invention'. 'I .claallllf-i v 1. A lining or finish for walls, ceilings, partitions, &c., constructed ot' ain-inner layer of 9b pulped board or other suitable material, an intermediate layerof netting or such like material, andfan outer layer .of plastic pr such like material, all substantially as described, for the purpose specified. ,l

2. A nishor lining for walls, ceilings, par-v titions,'&c., constructed of aninner layer of pulped board or othersuitable material, and

a layer ofl netting or such like material with a space between said two layers, and in combi` xoo nat-ion with a layer of plasticor such like niateria1 applied at the outside of theinterme diate layer and entered into the space between it and the-inner. layer, 4all substantially afs/described,y for the purpose specified` .x05 In testimony whereof I haye'hereunto set -f my hand in the presence. of two subscribing witnesses.
